Finding Nets to Construct 3D Shapes

Today in class we covered a multitude of concepts involving 3D Shapes and our Learning Goals prove that!

To review what we learned, here are 3 simple activities that you can do to show what you know!

First, can you look at a 3D shape and draw what the shape would look like from the top, side or bottom? These are called perspectives.

Next up, we talked about taking 3D shapes apart and flattening them to create a net. Why would this help us?

Time for you to problem solve! Click on the picture above to make it larger. Read the question and take time to leave a comment with your answer. Make sure you leave your name so I can give you credit!

Ready for a little challenge? I'd love to see what you create and share it with the rest of the 7th Graders on the blog! Search for me in Kmail and send me your pics!

And of course, I couldn't forget to share a video on 3D Shapes with you...

Transformations Small Group

 Yesterday's small group lesson after Class Connect was a review over the three different types of Transformations.

First up, we had to review our definitions. As we were reviewing them, we talked about different key words that could help us remember which type of transformation was which! On our next slides, we underlined those keywords and made examples of each type of transformation of an object about a 4 Quadrant graph.

And of course we had to do a bit of practice. For this assignment, I put it up on the whiteboard and we went through the triangle together. After that it was time for each student to get a turn and so I gave whiteboard privileges to all 17 students who showed up and we had a blast! 

 Now, if you are wondering what it should look like, here is an example of Mrs. S' copy that she printed out and worked along with you. This would be a great resource for you to put in your Math Notebook! You can download it for FREE here!

And of course, I couldn't leave you without a silly video! Don't forget to finish your Geometry Unit in Study Island by Friday, February 1st!

Coordinates, Coordinates, Coordinates...

The big change from 6th grade to 7th grade is going from only reading a graph in Quadrant 1 where all numbers are positive and then moving into 4 Quadrants with positive and negative numbers both.

As we reviewed the various location of positive and negative numbers in each quadrant and the location of the x and y-axis and origin, feel free to use your Coordinate Plane Flippable (check your Kmail) as a reference when you are working on your practice problems in Study Island and beyond.

Also, feel free to enjoy Groundhog Graphing and send in your pictures if you use them at home! I'd love to see your work!

3D Prisms and Pyramids

Are you having trouble distinguishing between prisms and pyramids? They are quite tricky so I'm here to help you out as you work through your practice problems and determine the differences between prisms and pyramids.

Recently we went over determining what various 3D Shapes were based on their characteristics. Based on what we worked on in class, quite a few of my students were having difficulty determining between prisms and pyramids.

To help make that a little easier when you are working on your Study Island I have created an Anchor Chart that you can print out and use when you are doing your practice problems.

Don't forget to complete your Study Island Geometry Assignments by February 1st! I'm looking forward to seeing those Blue Ribbons all across the board!
